Yep. It is the default mail program. I also couldn’t import a csv file. No way to change the columns to match the exported details from OL. But… using my mail server to import the same csv file just worked… Go figure.
Away at the moment but when I get home I’ll ensure all the details have been read. Also check the calendar import details. I set TB to use the carddav and caldev sync with my server and all will be fine. Once I get the details correct in TB I will revert to just local syncing (with my phone).
